At least to my knowledge, there is a possibility that they'll release an update tomorrow, or sometime along those lines. They did announce that they'll launch on March 31st (with Miitomo) an enhanced version of the eShop to be used on other devices, like computers, cellphones, etc.
I guess we can sorta predict that an update will come out for the 3DS and Wii U to be compatible with this, and possibly add some new features to the eShop in the consoles.
